Specification of Letters Patent.

Patented Jan. 5, 1915..

Application filed August 5, 1914. Seria1l lo. 855,106.

To all whom it may concern:

Be it known that I, VVILLIAM O. GLnnsoN, a citizen of the United States, residing at Bedford, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in SewenPipe Sections, of which the following is a specification.

This invention relates to improvements in sewer pipe sections used in building sewers, tunnels and other tubular conduits, and the object thereof is to provide a sewer pipe section at each end of which are slots, or recesses, for the reception of a metal tie bar which projects partly into each of the abutting ends of the adjacent sections, and has upturned portions which project up between the walls of each section and prevent the mortar, cement, or other binding material from running back into the said sections and also from falling down between the abutting ends of said sections.

The invention consists of the novel construction and arrangement of the parts and combination of parts hereinafter'more fully set forth in the following specification and pointed out in detail in the appended claims.

In the accompanying drawings-Figure 1 is a perspective view of a sewer pipe section embodying my invention. Fig. 2 is an end view of a section showing the position of the slots or recesses in the section to be used in the lower half of a sewer. Fig. 3 is an end view of Fig. 1 showing the metal tie bar in position in the slots or recesses in the end thereof. Fig. 4 is a side view, partly in section, of two sections placed together with the tie bar in position therein. Fig. 5 is an enlarged perspective view of one of the metal tie bars. Fig. 6 is a modification of the metal tie bar.

Referring to the accompanying drawings, forming part of this specification, and in which like reference numerals designate like parts throughout the several views thereof, 1 designates the upper and 2 the lower curved walls of a section of sewer pipe and united by a vertical web 3 extending the full length thereof. The sections are also provided with side walls 4 which are joined by a longitudinal web 5 extending the full length of said section. The walls and webs are all integral, and the side walls 4 and web 3 are each provided with a recess 6 at each end of the section between the bottom 2 and the longitudinal web 5 to receive the tie bar 7 which latter fits half into one end of one section and the other half fits into the end of the adjoining section. Each of said tie bars 7 has upward extending portions 8 and 9, on opposite sides which project up between the side walls 4 and the center web 3 and fill said space; the portion 8 being in one section and the portion 9 being in the abutting section. These tie bars prevent the mortar, cement or other binding material from dropping down between the sections, from flowing back into them, and form a tie for said sections. The sections that are used for the lower half of the sewer, are used in the inverted position and are provided with the recesses 6 adjacent the longitudinal web 5, as shown in Fig. 2, and the projections 8 and 9 project up to the bottom 2. The tie bars 7 are the same length as the width of the sections so that said sections will break joint in the usual manner.

In Fig. 6 I have shown a modification o the tie bar, the same being provided with the projections 10 at one side and the opposite side being slightly turned up at 11. In this modification the tie bar is placed into the slots in the end of the section, with the projections 10 extending upwardly the same as the projections of the other figures, and is provided with an upturned edge 11 which is flush with the outer end of the section, so that when two sections are fitted together the said upturned edges will abut.

Slight alterations in the construction and arrangement of the parts may be made in my present invention, within the scope of the appended claims.

Having fully described my invention, what I claim is:

1. A sewer pipe section having a top and a bottom wall and two side walls extending the full length thereof, said two side walls each having a recess in each end thereof, and a metal tie bar having a body portion adapted to fit partly into the recesses in the end of one section and partly into the recesses in the abutting section, said body portion having an upturned portion to prevent the binding material from flowing back into the section in which said upturned portion projects.

2. A sewer pipe section having a top and a bottom wall-and two side walls extending the full length thereof, said two side walls each having a recess in each end thereof, and a metal tie bar having a body portion adapted to fit partly into the recesses in the end on one section and partly into the recesses in the abutting section, said body portion having an upturned portion on opposite sides thereof to prevent the binding material from flowing back into the sections.

3. A sewer pipe section having a top and a bottom wall joined by a vertical web extending the full length thereof, and two side walls, the said vertical web and two side walls each having a recess in each end thereof, and a metal tie bar having a body portion adapted to fit partly into the recesses in the end of one section and partly into the recesses in the end of the abutting section, said body portion having upturned portions on opposite sides thereof adapted to bfit between the side walls and vertical we 4. A sewer pipe section having a top and Copies of this patent may be obtained for a bottom wall joined by a vertical web extending the full length thereof, and two side walls joined by a longitudinal web extending the full length thereof, the said vertical web and two side walls each having a recess in In testimony whereof I affix my signature :7

in presence of two witnesses.
